/*----- Revision history --------------------------------------------------*
*
* $Log: bres.c,v $
+ * Revision 1.6 2001/06/22 19:33:38 mdw
+ * Hack if there is no @_SC_OPEN_MAX@ or @OPEN_MAX@.
+ *
+ * Revision 1.5 2001/02/03 16:21:08 mdw
+ * Bug fixes: restore signals to their default dispositions, and set up the
+ * addresses properly when unpacking @hostent@ structures.
+ *
+ * Revision 1.4 2000/08/15 17:35:02 mdw
+ * (gethost, and others): Since @gethost@ actually uses @malloc@ rather
+ * than @xmalloc@, it's wrong to use @xfree@ on the result. Fixed the code
+ * to use the right freeing function on the right data.
+ *
+ * Revision 1.3 2000/06/17 10:38:35 mdw
+ * Track changes to selbuf interface.
+ *
+ * Revision 1.2 1999/10/30 11:28:39 mdw
+ * Fix include error, pointed out by Chris Rutter.
+ *
* Revision 1.1 1999/10/04 21:40:42 mdw
* Added background resolver from `fw'.
